Prompt Library: Cost and Caps
Modelling Agent Cost
Help me build a cost model for an agent, a distribution, not an average. THE TASK:
[description]. TOOL CALLS IN AN EASY CASE: [number]. IN A HARD CASE: [number]. SHARE THAT ARE
HARD: [estimate]. CONTEXT SIZE: [how much accumulates]. MODEL: [which]. VOLUME: [tasks per
month]. Estimate cost per task for easy and hard cases with your working, remembering later
steps carry more context. Give me a rough distribution with median and mean, and say how far
apart they are. Estimate monthly cost at my volume and at 5x. Recommend a per-task cap on
steps, time and cost, and what share would hit it. Compare against the human cost and tell me
the volume at which this stops making sense. Name the single change that would most reduce
cost and what it costs in capability. Flag that pricing changes.
